Abstract
The disclosed technology relates to methods, devices, systems and computer program products that facilitate access to metadata associated with a content. In one example, a method is described that includes receiving a multimedia content at a receiver device, extracting a watermark message from a first segment of the multimedia content, using at least a portion of the first watermark message to obtain additional information regarding the first segment of the multimedia content that includes the first watermark message, and associating and storing one or more values of the first watermark message and the additional information. The method further includes repeating the above operations to extract additional watermark messages from additional segments of the content and to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the additional watermark messages.
